I think I read something about this in the docs once but can't seem to find it now. Is there a way to extend the default sources rather than replacing them (eg. in

helm_chart(sources=...)

)? Bonus points if I can do this with

__defaults__

also

# Make `python_sources` targets recursive by default.
__defaults__({
  python_sources: dict(
    sources = [
      "**/" + glob for glob in
      python_sources.sources.default   
    ]
  ),
  ...
})
